ABSTRACT:
Plural television cameras situated at monitored sites, each assigned with a particular code, generate image signals of the sites. An image signal transmitting unit receives those signals and transmits an image transmission signal over a transmission a monitoring site. The transmission signal is so formed that one channel of the transmission line which is divided into plural channels is assigned to the transmission of an image signal of high priority sites so as, to reproduce a full motion image of the remote site at the monitoring site and all the signals from the other sites are transmitted on a time-sharing basis through the remaining channels to reproduce frame repetition images. The assignment of the channels is determined by the order (priority) of codes included in an instruction signal from an instruction signal transmitting unit at the monitoring site. An operator can select the order (priority) of the codes.
